I'm looking to swap out my water pump on my 1976 mercury 1150. I was looking at information about removing the lower unit. Some things I have read were to shift it into reverse before removing? Also, to discontinue the shift linkage I believe? Alothough it looked like the shifter was in the bottome unite when removing from a video I saw. So not sure if I need to disconnect any shifting linkage? Other things I have read were to just lossen the nuts and it will pop out. Just looking for some direction to make this process easy and smooth and make sure I don't botch anything. It seems that the new water pump base I got does not have the screw hole in it for the vent drain plug. Could I still use the new one without it or do I need to reuse the old one?Any advice is greatly appreciated!! Also, can I use parts degreaser to clean it up and then grease it back up?Thanks.
